Title: Process and plant for production of carbon monoxide and hydrogen
Inventor: GALLARDA JEAN
IPC: C01B32/40
Filed: 1999-02-18
Abstract: In the process of the invention, carbon monoxide is produced by partial condensation in a heat exchanger (310) from a condensed fraction (322) recovered at the base of a separator pot (320). Impure hydrogen (321) is produced at the head of pot (320) and purified by washing with nitrogen in a column (350). An ammonia synthesis mixture is produced from the hydrogen flow (353) collected at the head of the said column.      Carbon monoxide is furthermore produced from a fraction (351) collected at the base of the nitrogen-washing column (350).      All the columns and the exchanger are in a single cold box (400).

IPC: B60K5/02
Filed: 1999-06-23
Abstract: Disclosed is an all terrain vehicle with an improved engine and power train. The engine is located under the seat and the hingably seat provides for ready access to the engine for maintenance and repair. The engine is placed in the vehicle such that the crankshaft is parallel to the line of travel; that is to say that the crankshaft is in line with the longitudinal axis of the vehicle. The engine has a split output shaft; that is to say, two output shafts. One shaft extends forwardly of the engine to a front transmission on the front axle and the second extends rearwardly to a rear transmission on the rear axle. The output shafts run directly to the transmissions in a straight line. The front and rear output shafts are connected by gears which enables different ratios of revolution between the front and rear axle if necessary. The all terrain vehicle is also equipped with a unique parking gear which essentially locks the two output shafts to the transmission housing. There are a number of intermediate shafts such that power is transmitted from the crankshaft through two transmissions prior to reaching the output shafts. In addition, the gas tank is remote from the engine such that the cylinder head can be easily removed from the engine for servicing, repair and maintenance.

Abstract: A use enabling method and mechanism to enable use of a disabled game resident on multiple platform gaming machines. When a gaming operator elects to enable a particular disabled game, an enabling device of generates an encrypted Request Code (27) having components identifying the specific gaming machine and the specific game to be enabled. This Request Code (27) is then communicated through a communication coupling (55) to a compatible, mating encoder device (28) operated by the licensing game vendor or game manufacture. In response, the encoder device (28) generates an encrypted Enabling Code (31) which enables use only for the selected game or games, and only in the gaming machine (21) upon which the corresponding Request Code originated. Upon inputting the corresponding Enabling Code (31) into the enabling device (32) incorporated on the particular gaming device, the selected disable game or games may be subsequently enabled for use.

The socket groups on adjacent rows are offset such that they are oriented relative to one another such that each incoming tip receptacle of each of the socket groups in one row is more closely spaced to one of the other receptacles rather than the incoming ring receptacle of the adjacent row. The socket groups within one row may also be rotated relative to socket groups in an adjacent row. On the back of the protector panel, a plurality of pins are positioned to communicate with the socket groups. Wire pairs lead to and wrap around each of the pins. The wires are twisted about one another to a location near the pins at which point a first wire and a second wire of the wire pairs are separated to attach to their respective pins, wherein the number of twists per liner increment varies from one pair to another wire pair in close proximity.

Title: Displaying computer information to a driver of a vehicle
Inventor: BECKERT RICHARD D
IPC: B60R16/023
Filed: 1998-05-21
Abstract: A vehicle computer system includes a display device that is configurable for viewing by a driver of a vehicle while the vehicle is moving. The display device is responsive to a processor that executes application programs in conjunction with an operating system. A plurality of sensors are used to indicate the position of the display device, to indicate vehicle motion, and to indicate the state of a chosen vehicle control such as a parking brake. Application programs open display windows in conjunction with the operating system. In opening a window, an application program can indicate whether the window will contain driving-related information. The operating system monitors the sensors and prevents the display of non-driving-related windows to the driver when the vehicle is in motion or when it has the potential for motion. Specifically, the operating system in such a situation hides any windows that have not been specified as being driving-related. Initially, all windows are assumed to contain non-driver related information;  hence, they are hidden until it is determined what type of information they display.

Title: Method for generating a random number on a quantum-mechanical basis and random number generator
Inventor: SCHMITZER HEIDRUN
IPC: H03K3/84
Filed: 1999-05-28
Abstract: The invention relates to a process for the generation of a random number on a quantum-mechanical basis and to a random-number generator, in particular for implementing the process. The invention is based on the fundamentally random path selection of a quantum particle at a beam splitter (8, 18), the outputs (11, 12, 16, 17) of the beam splitter (8, 18) being associated with detectors (D1, D1', D2, D2') for detecting the particles. The detectors/counting events of the detectors represent different numerical values of the random sequence. Through the generation according to the invention of a multi-particle state in the output channel (11, 12, 16, 17) of the beam splitter (8, 18) and therefore through a plurality of particles impinging on the detector (D1, D1', D2, D2'), the response probability of the detector and therefore the probability of a usable counting event for each multi-particle state generated by the source (3, 3') is in advantageous manner significantly increased.  Consequently, a random sequence can be built faster and more reliably than in the case of single-particle detection.

IPC: G08B17/00
Filed: 2000-02-04
Abstract: Currently there are many different types of smoke detectors. There are ones designed for detecting smoke that is emitted from fires and there are detectors that are designed for detecting carbon monoxide emitted from various sources (eg. furnaces, cars, fires). Both emissions are deadly and have caused numerous deaths. Today laws have been passed making it mandatory for all households to have working detectors but there have been many reported cases of people dying not because they did not have the detectors but because the batteries had been removed and not replaced. This invention will prevent both adults and children from easily removing the batteries from these life saving devices therefore allowing smoke and carbon monoxide detectors to be functioning at all times.

Abstract: Eliciting a systemic antitumor immune response, in a patient who presents with or who is at risk of developing multiple metastatic tumors of a given cell type, entails, in one embodiment, inoculating a tumor in the patient with a pharmaceutical composition consisting essentially of (A) a herpes simplex virus (HSV) that infects tumor cells but that does not spread in normal cells and (B) a pharmaceutically acceptable vehicle for the virus, such that an immune response is induced that is specific for the tumor cell type and that kills cells of the inoculated tumor and of a non-inoculated tumor. In another embodiment, the pharmaceutical composition also comprises a defective HSV vector which contains an expressible nucleotide sequence encoding at least one immune modulator. In another embodiment, the pharmaceutical composition contains a second HSV that infects tumor cells but that does not spread in normal cells. According to the latter approach, both the first HSV and the second HSV may have genomes that comprise, respectively, an expressible nucleotide sequence coding for at least one immune modulator. In another embodiment, the pharmaceutical composition comprises, in addition to a herpes simplex virus (HSV) that infects tumor cells but that does not spread in normal cells, a viral vector comprising at least one expressible nucleotide sequence coding for at least one immune modulator.
